National Weather Service: Wyoming’s Water Supply Above Average

Officials with the National Weather Service say Wyoming’s water supply is, for the most part, well above average for the month of March.

NOAA hydrologist Jim Fahey says precipitation in February was 180 percent of normal, which is bolstering current water year precipitation estimates to roughly 135 percent of normal.

The February rainfall total ranges from 360 percent of average for the Clark Fork/Yellowstone and Shoshone River drainages, to near 100 percent of normal near the Cheyenne and Niobrara Basins in eastern Wyoming.

Fahey says mountain snow pack also remains well above average, generally ranging from 120 percent to 135 percent of normal, depending on what part of the state you're in.

NWS is also expecting above normal streamflows for the Powder, Tongue, Shoshone and Wind River watersheds, ranging between 110 and 125 percent. Below average streamflows are expected for the Little Wind and Sweetwater watersheds, however.

Fahey also says reservoir storage remains about 10 percent below average for early March.
